CC2650: reading report command in cc2650

Part Number:CC2650

i am using cc2650 an an ED with z-stack 1.2

and cc2538 as a CD

i want to send report command from 2538 to 2650 ( zcl_sendReport_cmd) i know how to do that

i search in 2650 mainly in DLSApp_processZStackMsgs() to find the case of  ZCL_CMD_REPORT to process the incoming Report command from  2538 but i didn't find any thing

so how to do this step ?
